2. the cosine curve below represents the amount of precipitation by season in a region of the
savannah of africa. the highest average amount of precipitation is 170 cm/month in the
rainy season, but it goes down to 2 cm/month in the dry season. based on the values, what
represents the amplitude of this cosine function?

-7/8

step-by-step explanation:

instead of subtracting you add the -6/8 and -1/8

b

step-by-step explanation:

u take $75 minus $60.the anwer/original($75)multiply by 100

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
